<h1 class="title toc-ignore">Project Profiles</h1>



<div id="introduction" class="section level2">
<h2>Introduction</h2>
<p>Starting with <code>renv 0.13.0</code>, it is possible to activate
and switch between different profiles associated with a project. A
profile can be thought of as a different mode in which a project is
used. For example:</p>
<ul>
<li>A “development” profile might be used when developing and testing a
project,</li>
<li>A “production” profile might be used for production
deployments,</li>
<li>A “shiny” profile might be used when running the Shiny
application.</li>
</ul>
<p>At its heart, activating or using a particular profile implies using
a different set of paths for the project library and lockfile. With
this, it is possible to associate different packages, and different
dependencies, with different workflows in a single project using
<code>renv</code>.</p>
</div>
<div id="usage" class="section level2">
<h2>Usage</h2>
<p>By default, <code>renv</code> projects use the “default” profile,
which implies that library and lockfile paths are set in the typical
way. To activate a particular profile, use:</p>
<pre><code>renv::activate(profile = &quot;dev&quot;)</code></pre>
<p>This creates a profile called <code>&quot;dev&quot;</code>, and sets it as the
default for the project, so that newly-launched R sessions will operate
using the <code>&quot;dev&quot;</code> profile. After setting this and
re-launching R, you should see that the default library and lockfile
paths are resolved within the <code>renv/profiles/dev</code> folder from
the project root.</p>
<p>Alternatively, if you want to activate a particular profile for an R
session without setting it as the default for new R sessions, you can
use:</p>
<pre><code>Sys.setenv(RENV_PROFILE = &quot;dev&quot;)</code></pre>
<p>and <code>renv</code> will automatically use that profile as
appropriate when computing library and lockfile paths. Similarly, from
the command line, you might enforce the use of a particular profile in
an <code>renv</code> project with:</p>
<pre><code>export RENV_PROFILE=dev</code></pre>
<p>With that set, <code>renv</code> would default to using the
<code>&quot;dev&quot;</code> profile for any newly-launched R sessions within
<code>renv</code> projects.</p>
<p>To activate the “default” profile used by a project, use:</p>
<pre><code>renv::activate(profile = NULL)</code></pre>
</div>
<div id="managing-profile-specific-dependencies" class="section level2">
<h2>Managing Profile-specific Dependencies</h2>
<p>Profile-specific package dependencies can be declared within the
project’s top-level <code>DESCRIPTION</code> file. For example, to
declare that the <code>shiny</code> profile depends on the <a href="https://shiny.rstudio.com/">shiny</a> and <a href="https://www.tidyverse.org/">tidyverse</a> packages:</p>
<pre><code>Config/renv/profiles/shiny/dependencies: shiny, tidyverse</code></pre>
<p>If you’d like to also declare that these packages should be installed
from a custom remote (analogous to the <code>Remotes</code> field for
the default profile), you can define those remotes with a separate
field:</p>
<pre><code>Config/renv/profiles/shiny/remotes: rstudio/shiny, tidyverse/tidyverse</code></pre>
<p>These remotes will then be respected in calls to
<code>renv::install()</code>.</p>
<p>The packages and remotes must be specified separately, as
<code>renv</code> cannot determine the package name associated with a
particular remote without explicitly resolving that remote. Remote
resolution normally requires a web request, which <code>renv</code>
tries to avoid in “regular” dependency discovery.</p>
<p>If you’d prefer that only the packages enumerated in this field are
used, you can opt-in to using <code>&quot;explicit&quot;</code> snapshots, and
leave the <code>Imports</code>, <code>Depends</code> and
<code>Suggests</code> fields blank:</p>
<div class="sourceCode" id="cb7"><pre class="sourceCode r"><code class="sourceCode r"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a>renv<span class="sc">::</span>settings<span class="sc">$</span><span class="fu">snapshot.type</span>(<span class="st">&quot;explicit&quot;</span>)</span></code></pre></div>
<p>When set, only the dependencies listed in the project
<code>DESCRIPTION</code> file will be used when the lockfile is
generated. See <code>?renv::snapshot</code> for more details.</p>
